The figure shows a box being pulled up a ramp inclined at 23° from the horizontal. Use the following information to solve the problem. BA= force of gravity, |BA| = weight of the box 23° = 23° AC magnitude of the force needed to pull the box up the ramp |BC| = magnitude of the force of the box against the ramp If the box weighs 110 pounds, find the magnitude of the force needed to pull it up the ramp. The magnitude of the force needed to pull the box up the ramp is approximately pounds. (Type an integer or decimal rounded to the nearest tenth as needed.)

The helicopter view in the figure below shows two people pulling on a stubborn mule. (Take F₁ = 137 N and F₂ = 74.0 N.) 75.0° direction 60.0⁰ x (a) Find the single force that is equivalent to the two forces shown. 149.56 magnitude Your response differs from the correct answer by more than 10%. Double check your calculations. N 23.65 X Your response differs from the correct answer by more than 10%. Double check your calculations. counterclockwise from the +x-axis (b) Find the force a third person would have to exert on the mule to make the net force equal to zero. magnitude N direction counterclockwise from the +x-axis

Four forces act on an object, given by  A = 38.3 N east, B = 45.3 N north, C = 70.7 N west, and D = 88.7 N south.  (Assume east and north are directed along the +x-axis and +y-axis, respectively.) (a) What is the magnitude of the net force (in N) on the object?   (b) What is the direction of the force? (Enter your answer in degrees counterclockwise from the +x-axis.)

As you will see in a later chapter, forces are vector quantities, and the total force on an object is the vector sum of all forces acting on it. In the figure below, a force F, of magnitude 6.70 units acts on a crate at the origin in a direction 0 = 26.0° above the positive x-axis. A second force F, of magnitude 5.00 units acts on the crate in the direction of the positive y-axis. Find graphically the magnitude and direction (in degrees counterclockwise from the +x-axis) of the resultant force F, + F,. magnitude units direction Counterciockwise from the +x-axis

Braces are used to apply forces to teeth to realign them. Shown in this figure are the tensions applied by the wire to the protruding tooth. T = 27.5 N What is the magnitude of the net force that is exerted on the tooth (in N) if the tension in the wire is 27.5 N?

A bag of cement of weight 326 N hangs from three wires as shown. Two of the wires make angles ₁ = 60.0° and 9₂ = 25.0 ° with the horizontal. If the system is in equilibrium, find the tension T₂ in the wire. Specify your answer as an integer i.e. with no decimals. Do not include units. Ti 0₁ T3 0₂ T₂ 10 W
